Hybrid tea rose plant named &#39;Meizoele&#39;

ABSTRACT

A new and distinct variety of Hybrid Tea rose plant is provided which abundantly forms attractive double bicolored blossoms that are yellow bordered with red in coloration. The plant exhibits a. vigorous growth habit, semi-glossy dark green foliage, and very good disease resistance. The dark green foliage contrasts nicely with the lighter colored blossoms. The new variety is particularly well suited for growing as attractive ornamentation in the landscape such as in parks and gardens.

This is a Continuation of U.S. Plant Patent Application No. 10/832,331, filed Apr. 27, 2004, which is a Continuation of U.S. Plant Patent Application No. 10/288,426, filed Nov. 6, 2002 (now abandoned), which is a Continuation of U.S. Plant Patent Application No. 09/499,673, filed Feb. 8, 2000 (now abandoned).

BOTANICAL/COMMERCIAL CLASSIFICATION

Rosa hybrida/Hybrid Tea Rose Plant

VARIETAL DENOMINATION

cv. ‘Meizoele’

SUMMARY OF THE INVENTION

The new variety of Hybrid Tea rose plant was created by artificial pollination wherein two parents were crossed which previously had been studied in the hope that they would contribute the desired characteristics. The female parent (i.e., the seed parent) of the new variety was the ‘Meinarval’ variety (non-patented in the United States). The male parent (i.e., the pollen parent) was the ‘Lapdal’ variety (non-patented in the United States). The parentage of the new variety can be summarized as follows: ‘Meinarval×Lapdal.’

The seeds resulting from the above pollination were sown and small plants were obtained which were physically and biologically different from each other. Selective study resulted in the identification of a single plant of the new variety.

It was found that the new variety of Hybrid Tea rose plant of the present invention possesses the following combination of characteristics:

-   -   (a) exhibits a vigorous growth habit,     -   (b) abundantly forms attractive double bicolored blossoms that         are yellow bordered with red in coloration,     -   (c) forms attractive dark green semi-glossy foliage that         contrasts well with the blossoms, and     -   (d) is particularly well suited for growing as attractive         ornamentation in the landscape.

The disease resistance of the new variety is very good.

The new variety of the present invention can be readily distinguished from its parental varieties. The ‘Meinarval’ female parent forms very elongated high-pointed buds that are distinct from the shorter and globular buds of the new variety. The ‘Lapdal’ male parent forms dissimilar cream blossoms that are edged with carmine.

The new variety of the present invention also can be readily distinguished from the ‘Meinomad’ (U.S. Plant Pat. No. 8,248) and ‘Meibosnio’ (U.S. Plant Pat. No. 12,876) rose varieties. More specifically, the ‘Meinomad’ variety forms flowers having a subtantially larger diameter of approximately 14 cm on average, and the ‘Meibosnio’ variety forms flowers having substantially more petals that commonly number approximately 70 to 75 flower on average.

The new variety well meets the needs of the horticultural industry and can be grown to advantage in parks and gardens.

The new variety has been found to undergo asexual propagation in France by a number of routes, including budding, grafting, and cuttage. Asexual propagation by the above-mentioned techniques in France has shown that the characteristics of the new variety are stable and are strictly transmissible by such asexual propagation from one generation to another.

The new variety has been named the ‘Meizoele’ variety.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying photograph shows as nearly true as it is reasonably possible to make the same, in a color illustration of this character, typical specimens of the plant parts of the new variety. The rose plants of the new variety were two years of age and were observed during October while budded on Rosa froebelli understock and growing in outdoors at Le Cannet des Maures, Var, France. Dimensions in centimeters are indicated at the bottom of the photograph.

DETAILED DESCRIPTION

The chart used in the identification of the colors is that of The Royal Horticultural Society (R.H.S. Colour Chart). The description is based on the observation of two year-old plants during October while budded on Rosa froebelli understock and growing outdoors at Le Cannet des Maures, Var, France. The coloration in common terms precedes reference to the chart in some instances. Such terminology is to be accorded its ordinary dictionary significance.
